I'm trying to use Endpoints, so I created an Entity as follows:

我正在尝试使用端点，所以我创建了一个实体，如下所示：

@Entity
@Table(name="Users")
@NamedQuery(name="User.findAll", query="SELECT u FROM User u")
public class User implements Serializable {
    private static final long serialVersionUID = 1L;

    @Id
    private String id;

    private String password;

    private String username;

    public User() {
    }

    public String getId() {
        return this.id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getPassword() {
        return this.password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getUsername() {
        return this.username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

}

Then, I right clicked on the class Google appEngine WTP --> generate Cloud Endpoint Class....

然后，我右键点击Google appEngine WTP类 - >生成Cloud Endpoint Class ....

I'm following the getting started tutorial https://developers.google.com/eclipse/docs/endpoints-js

我正在按照入门教程https://developers.google.com/eclipse/docs/endpoints-js

My Index.html is as follows:

我的Index.html如下：

<html>
  <head>
    <meta http-equiv="content-type" content="text/html; charset=UTF-8">
    <title>Hello App Engine</title>
    <script src="https://apis.google.com/js/client.js?onload=init">
    </script>
  </head>
  <body>
    <h1>Hello App Engine!</h1>
      <script>
        function init(){
         var ROOT = 'http://localhost:8080/_ah/api';
            gapi.client.load('libuserendpoint', 'v1', function() {
              alert("hello");
            }, ROOT);
        }
    </script>
  </body>
</html>

2 个解决方案

#1

The correct URL for Google APIs Explorer in your local environment is localhost:8080/_ah/api/explorer

本地环境中Google API Explorer的正确URL是localhost：8080 / _ah / api / explorer

#2

I'm guessing you may need a slash to start the URL, so maybe the URL needs to look like:

我猜你可能需要一个斜杠来启动URL，所以URL可能需要如下所示：

_ah/api

Instead of:

代替：

http://localhost:8080/_ah/api

I saw the following question which made me think of this:

我看到以下问题让我想起了这个问题：

google cloud enpoint callback after update

更新后google cloud enpoint回调
